NEW METHODOLOGICAL APPROACH TO MORPHOLOGICAL

The way of characterizing an interfacial morphology and its relation t o the mechanism of transformation of a solid are discussed in this pap er for the particular case of electrochemical dissolution. Several par ameters, useful in the description of the morphology and its variation with time, are proposed. Moreover, a physical model and its mathemati cal formulation are developed in order to predict the morphological ch anges of the interface. The results of numerical and analytical soluti ons to this problem are compared with experimental data obtained for t wo cases: aqueous corrosion of copper and electrolytic polishing of a stainless steel.
